Any use one of these things? I don't have the factory monitor, which I wouldn't trust anyway, and would love to have something to keep an eye on mileage. Are there any data points that the scanguage would display that are specific to the PSD, or a diesel?
Yeah, we install flowscans on boats alot at work. Kinda neat really. You have a flow meter on the inlet side, and a flow meter on the return side, and it calculates the difference to give you a gallons per hour rate of use.
Not sure what they have to tie into the speedo sensor of a powerstroke to give you a true on the fly MPG reading tho. Never messed with the automotive side.
